Another type of fish is encountered in the underwater section of the Land of the Livid Dead. These fish swim passively about and do not react to Rayman's presence. Additionally, Céloche, the giant tripod boss of the world, releases a massive metallic fish at the start of the battle; it is this device that deploys the homing missiles that can defeat the boss. Similar metal fish can be found in the Summit Beyond the Clouds, specifically in the Looming Sea segment. These giant fish are attacking the boat Rayman and Globox are using to get to André's secret hideout. Once the summit comes into view, the fish stop attacking.

Much like in some of the swamp infested waters of Rayman 2, fish bones can be seen piled up in various areas throughout the game, acting as static barriers that require breaking with an attack to progress.
